The 2017 Rogers Cup presented by National Bank was a tennis tournament played on outdoor hard courts.

It was the 128th edition (for the men) and the 125th (for the women) of the Canadian Open.

The tournament was part of the ATP World Tour Masters 1000 of the 2017 ATP World Tour, and of the WTA Premier 5 tournaments of the 2017 WTA Tour, and is also a 2017 US Open Series event.

Seedings are based on ATP rankings as of July 31, 2017.

Because the tournament takes place two weeks later than in 2016, the points defended from last year was not superseded within a 52-week run, the results during the 52-week period were from 2016 Los Cabos Open.
